Pour Faire Sauon Qui Delgresse & Oste Toute Tache Que Ce Soit
"Prens alun de roche brusle vne liure, metz le en pouldre: racines de flambes de florence puluerisees demie liure, vng oeuf fraiz, deux liures & demie sauon blanc: incorpore lesdictes pouldres auec loeuf & le sauon, & en fais pelottes, & si tu vois que vng seul oeuf ne suffise, prens en tant que il te plaira, ou que tu verras estre de besoing a faire ta paste. Et quant tu vouldras essuyer la tache, prens de leaue commune, & en baigne ou laue ladicte tache des deux costez du drap, & puis frotte auec la balotte ou pelotte susdicte & drap sur drap: cela faict, essuye lordure auec eaue fresche, en tordant le drap pour faire saillir la gresse. puis relaue ledict drap auec eaue fresche, & il demourera nect."
English Translation
"Take one pound of burnt rock alum, put it into powder; half a pound of powdered roots of iris of Florence, one fresh egg, two and a half pounds of white soap. Mix the said powders with the egg and the soap, and make small balls of it; and if you see that one egg is not enough, take as many as you like or as you see necessary to make your paste. And when you want to remove a stain, take common water and bathe or wash the said stain on both sides of the cloth, then rub with the aforementioned ball, rubbing cloth against cloth. When done, remove the dirt with fresh water, wringing the cloth to bring out the grease, then wash the said cloth again with fresh water and it will remain clean."
Note on the Original Text
Like many early-modern recipes, this text is heavy on process and light on exact measurements by modern standards. Ingredients are listed by the pound (liure), so we've had to convert to metric, and there is flexibility in the amount of egg used (as needed to form the paste). Instructions are practical, written for someone familiar with household tasks, omitting precise times or temperatures. Expect antique spelling quirks—from 'auoir' for 'avoir' to the French long 's' (ſ) and unique phrasing, such as 'ossuire la tache' (to wipe the stain). The recipe was not meant to be read by everyone, but rather by literate householders—probably with experience, expected to improvise when the texture seemed off.

This remedy, written in the mid-16th century and published in Lyon in 1541 by the Frellon family, comes from a manual of practical secrets for home care, perfumery, and health. The text, translated from Italian into French, was part of a new wave of Renaissance publishing that blended household management, medical wisdom, and the arts of cleanliness. Recipes like these were prized for their promise to remove almost any stain or grease, long before modern detergents and stain removers existed. Such books circulated among the literate classes, especially women who managed large households. The specific recipe is not a culinary dish, but rather a sophisticated laundry and cleaning aid, hinting at the high priority placed on cleanliness and fine fabrics during the Renaissance. Its inclusion shows a world where the domestic sphere was both a place for innovation and closely guarded knowledge.

Renaissance-era households would have used a mortar and pestle for grinding solid ingredients into powder, such as the alum and orris root. A large earthenware or wooden bowl would be used to combine the powders, eggs, and soap, kneading them together by hand. The soap would be hand-shaved if not already in flakes. For use, ordinary linen cloths and buckets or basins of water were employed. Fabrics would be wrung out by hand, with vigorous rubbing between cloths as described. No modern laundromat—just practical kitchen or laundry tools within the home.

Ingredients
- 1 pound (16 oz) burnt alum (aluminum potassium sulfate, calcined)
- 8 ounces (1/2 pound) powdered orris root (Florence iris root) or substitute with another mild root starch if unavailable
- 1 to 2 fresh eggs, as needed
- 2.5 pounds (40 oz) white soap (unscented, pure, similar to traditional Castile soap)
- Fresh water (for rinsing)
Instructions
- Begin by taking 1 pound (16 oz) of burnt alum (aluminum potassium sulfate, calcined in advance), and grind it into a fine powder.
- Add 8 ounces (1/2 pound) of powdered Florence iris root (known today as orris root), and combine thoroughly.
- Crack open a fresh egg and mix it into the powders.
- Next, measure 2.5 pounds (40 oz) of white soap—unscented and simple, akin to a traditional Castile soap.
- Knead all these ingredients together, adding more eggs as necessary, until a workable, slightly sticky paste forms.
- Shape the dough into small balls or pellets.
- When ready to use, dampen the stain on the fabric from both sides with plain water.
- Rub one of the cleaning balls directly onto the stain, sandwiching the area between two pieces of cloth and rubbing cloth on cloth.
- Rinse the affected area with fresh, clean water, wringing the fabric as you go to remove the loosened grease and dirt.
- Rinse again, and allow to dry—your fabric should be left clean and spotless.

Cooking Estimates
It takes about 25 minutes to grind, mix, and knead the ingredients, and there is no actual cooking time. This recipe makes about 40 small cleaning balls, with each ball used for one cleaning session. Each ball has around 25 calories since the ingredients are mostly soap, alum, and a small amount of egg and orris root.
